Two. How to disassemble a door lock with a broken key that has been locked.
Sometimes, you might accidentally lock a handle, making it difficult to open. You can try using a thin, pointed tool. The sharper the tool, the better. First, position the handle and then push on the locking mechanism (also known as the spindle) without letting it come into contact with the lock body. Use the tool to apply pressure to the spindle in the direction of its movement. You may need to try several times. If the above methods don't work, consider hiring a professional locksmith. Locksmiths typically have specialized tools and techniques for opening locks.
